IEHP UM Subcommittee Approved Authorization Guidelines Referrals to Pain Management Specialists

Transcription

1 IEHP Policy: Based on a review of the currently available literature and community standards of practice, the IEHP UM Subcommittee will consider referrals to Pain Management Specialists medically necessary and appropriate under the following three criteria (1, 2, or 3): 1. The patient has chronic non-malignant (non cancer-related) pain lasting at least 3-6 months that meets the following criteria (A, B, C & D): A. The patient s pain is unresponsive to conservative care. Evidence of a failed trial of conservative care should include: o Failure of at least 2-3 different classes of medications appropriate to the type of pain (i.e., nociceptive/somatic pain vs. neuropathic pain vs. psychogenic pain) including: NSAIDs Acetaminophen Opioids Muscle relaxants Anti-depressants (SSRI s, tri-cyclics etc ) Anti-epileptic drugs (gabapentin, pregabalin etc ) AND o Failure of at least one physical treatment modality including any of the following: Ice, rest and activity modification Bracing, taping or other immobilization Physical and/or occupational therapy Chiropractic Care (for eligible Medicare members) Note: Any contraindications to the above listed treatment modalities must be specifically documented in the patient s medical records. B. An appropriate diagnostic work-up of the patient s pain has been performed. At a minimum, an appropriate diagnostic work-up should include documentation of the following: Sixth St, Rancho Cucamonga, CA Tel (909) Fax (909) Visit our web site at: A Public Entity

2 Page 2 of 5 OR a. A complete and accurate history and physical exam have been performed. b. Appropriate diagnostic testing has been done including, but not limited to, the following: i. For nociceptive pain: x-rays, ultrasounds, or other initial imaging tests to rule out the presence of structural lesions and/or significant anatomical pathology. ii. For neuropathic pain with a radicular component: electrodiagnostic studies (EMG/NCS) and/or an MRI to differentiate between a peripheral entrapment neuropathy versus neural impingement at the spinal cord. C. Treatable underlying causes of pain have been addressed by the PCP and the appropriate specialists. For example: a. Pain due to an autoimmune condition (RA, SLE, etc ) or fibromyalgia should be assessed and treated by a rheumatologist. b. Pain due to a neurological condition (MS, migraines, Trigeminal Neuralgia, Spinal or Brain Lesion) should be addressed and treated by a neurologist and/or neurosurgeon. c. Pain due to malignancy (tumors, sequelae of radiation/chemotherapy treatment) should be assessed and treated by a hematologist, oncologist, radiation oncologist or similar specialist. d. Pain that is caused by and/or complicated by psychosocial conditions (anxiety, depression, secondary gain) or associated with substance abuse-should be assessed and treated by the appropriate mental health provider(s) including psychiatrists, psychologists, therapists and addiction medicine specialists. D. There is documentation that the pain is causing the patient significant functional impairment (inability to perform usual activities of daily living) and/or is contributing to deterioration in their overall health. 2. Once 3-6 months of conservative modalities have failed and an appropriate work-up has been completed, the patient s condition is determined to require interventional procedures not typically performed by PCP s or other specialists. Examples include: a. Radiofrequency Neurotomy (ablations) b. Epidural Steroid Injections c. Facet Blocks/Medial Branch Blocks d. Sacroiliac Injections e. Trigger Point Injections f. Sympathetic Ganglion Blocks g. Peripheral Nerve Blocks

Immediate referral to a Pain Management Specialist or other appropriate specialist may be considered under the following circumstances: a. Evidence of polytrauma b. Evidence of substance abuse, non-compliance and/or secondary gain (opioid dose escalation, use of illicit substances, violations of pain contact, diversion of narcotic medications etc ) c. Evidence of significant psychiatric co-morbidities that are being exacerbated by chronic pain (for example, major depression, bipolar disorder etc ) d. Pain due to malignancy e. The presence of red flags including but not limited to: progressive motor weakness, sensory deficits, gait disturbances, bowel/bladder dysfunction, unexplained weight loss etc Note: In using these criteria to make final determinations regarding the medical necessity of referrals to pain management specialists, IEHP reserves the right to take into consideration the specific circumstances of each patient s unique clinical condition. Apollo Guidelines : According to these guidelines, pain management services (including medications, interventional techniques, behavioral methods, and physical treatments) may be covered when there is persistent pain > 3 months that is unresponsive to active management by the primary care physician or in-plan specialists evidenced by adjustment/escalation in medication management and failure of other appropriate conservative modalities. National Institute for Health and Care Excellence (NICE) 2 : Consider referring the person to a specialist pain service and/or a condition-specific service at any stage, including at initial presentation and at the regular clinical reviews if: They have severe pain Their pain significantly limits their lifestyle, daily activities (including sleep disturbance) and participation OR Their underlying health condition has deteriorated Department of Veterans Affairs/Department of Defense (VA/DOD) 3 : Consider referral to a Pain Management Specialist in the following situations: Patient with complex pain conditions or polytrauma Patient with significant medical comorbidities that may negatively impact opioid therapy Patient who is unable to tolerate increased pain or physical withdrawal symptoms arising from opioid tapering when opioid therapy is being discontinued Opioid induced hyperalgesia or opioid tolerance is suspected

Health Plan of Nevada 6 : In general, a Pain Management referral should be made when: Pain has lasted > 6 months despite conservative therapy, or Pain is from an acute event that may benefit from early intervention (i.e. acute disc herniation) Provider feels there is a specific intervention that Pain Management can offer (i.e. procedure) Surgery is contemplated or eliminated as option by appropriate specialist Recommendations sought for medication management State of Colorado Department of Labor and Employment 7 : "Consultation or referral to a pain specialist should be considered when the pain persists but the underlying tissue pathology is minimal or absent and correlation between the original injury and the severity of impairment is not clear. Consider consultation if suffering and pain behaviors are present and the patient continues to request medication, or when standard treatment measures have not been successful or are not indicated."

Among these documents, those which specifically addressed the criteria for referral of patients to pain management specialists by primary care physicians were included in the current IEHP UM Subcommittee Guideline.
